MEANS FOR PREVENTING LOCOMOTIVE DRIVING-WHEELS FROM SPiNNING.

SPECIFICATION forming part of Letters Patent No. 296,576, dated April 8, 1884.

Applicaiion filed August 17, 1883. (No model.)

To all whom it may concern:

Be it known that l, Mnmson L. JOHNSON, of Galena, in the county of JovDaviess and State of Illinois, have invented a new and useful Improvement in Means for Preventing Locomotive Driving Wheels from Spinning, which improvement is fully set forth in the following-specification, reference being had to the accompanying drawings, in which- Figure l is a representation of a portion of of a locomotive, showing my invention applied; and Fig. 2 is a transverse sectional view of the same.

The object of my invention is to prevent the driving-wheels of locomotives from spinning or slipping on the rail. This I accomplish by placing in the smoke-box of a locomotive, as shown in the drawings, two pans of funnel shape, AA, opposite each other and facing the blast-pipes H'H. The smaller ends of the pans extend throngh the sides of the smoke-box, where eachiiias a valve, 0 O, and where the pipes G G are connected on either side, which run back to a point midway between the driving-wheels and the rails. I also place at the top of the smoke-box, at the point where the smoke -stack I is affixed, a damper, D, with a crank-arm, E, attached, and a controlling-rod, F, which leads back to the cab of the locomotive. The pans A A are covered at their face with a grating of wirecloth, to prevent the larger cinders from entering. The valves 0 G, if so desired, can be attached to the rod F, and operated in connection with the damper D. By pushing the rod F forward, it closes the damper and partly cuts off the draft that should go through the stack 1, and all the smoke, dust, and small cinders that cannot escape through the small opening K are equally divided and are forced through the pans A A and the pipes GG, vand are deposited on the rail directly under the driving-wheels, the heat of the smoke and dust drying the rail, if it be moist; and the cinders being ground or crushed between the wheel and the rail increases the friction, there by enabling the wheel to keep the rail and preventing it from slipping or spinning.

WVhat I claim as my invention or discovery, and desire to secure by Letters Patent, is-

The combination, with the wire-ganze-covered pans, arranged within the smokebox of a locomotive, having their lateral tubes provided with valves, the pipes G G, leading therefrom to the traclcrails, the damper D, provided with a central annular opening, its

with the controlling-rod F, and the blastpipes H H, arranged within the smoke box, all adapted to operate substantially as shown and described.
